| 4 | This metadata file instructs the Gravity Service Binder to |
| 5 | create one instance of "SpellCheckServiceImpl". It also |
| 6 | tells the generic activator that this instance implements the |
| 7 | "SpellCheckService" service interface and that it has an |
| 8 | aggregate dependency on "DictionaryService" services. Since |
| 9 | the service dependency on dictionary services has a lower |
| 10 | cardinality of one, the generic activator will create the instance |
| 11 | and offer its spell check service only when there is at least |
| 12 | one dictionary service available. The service dependency is |
| 13 | "dynamic", which means that dictionary service availability |
| 14 | will be monitored dynamically at runtime and it also tells the |
| 15 | generic activator which methods to call when adding and removing |
| 16 | dictionary services. |
